Referring more particularly to Figs. 1 to 7 of the drawings, the machine embodies a frame I composed of angle irons and having depending bearing members 2 in which is journaled the offset portion of a crank axle 3 having ends 4, 4 forming journals on which wheels 5, 5 are mounted to turn. At the front end a link 6 is pivotally attached at 'I to the side bar 8 of frame I. A clevis Il) provided with a pin I I is bolted at I2, I2 to link 6, whereby the machine can be attached to a tractor, not shown.

Pans I5, I5 that normally contact the ground on either side of the vines are attached to frame I by a sub-frame comprising angle bars I6, I6 at the front end thereof and rear cross bar I 'I pivotally carried in hanger bearings I8, I8 attached to bars I9, I3 of frame I. A conveyor belt 20 is mounted in each of the pans I5, I5. Each of the belts 20 moves on a roller 2| in the front end. Roller 2l has bearings in the side walls 22, 22 of pans I5, I5. Belts 20 run parallel with the ground for a short distance, then upwards at an inclined angle at the rear end over roller 23 mounted to turn with shaft 24 having bearings in hangers 25, 25 fixed to the back wall of rear upwardly inclined chute 26. The lower part of each of the chutes 26, 26 rests in the rear part of pan I5..

Direction rollers 21, 21, 21 having bearings in side walls 28, 28 of chute 26 aid in holding the conveyor belts ZIJ at their required angle in their respective chutes 26, 26. There is employed for this purpose also narrow arcuate members 29, 29 supported at their opposite edges by lugs 30 riveted or welded to side walls 28, 28 of chute 26. A member consisting of an inclined ilat sheet 3| having a curved lower end 32 is disposed in parallel relation to and spaced from conveyor belt 20 in each instance, whereby to hold the beans against the conveyor belts 20, 2Il. It is supported at one end by links 33, 33 pivoted at 34, 34 to the side walls 28, 28 of chute 26, and at the other pivoted to brackets 35, 35 welded to the top surface of sheet 3|, whereby to allow for exbility at this location.

The means for moving each of the conveyor belts 20, 20 is the sa-me for each belt. It comprises a sprocket wheel 40 mounted to turn with shaft 24 mentioned above. A sprocket chain 42 connects sprocket 40 with sprocket 43 mounted to turn with shaft 44 supported cross wise of the machine in hanger brackets 45, 45 welded to overhead cross angle iron 46 of frame I.

Shaft 44 is rotated by power shaft 50 carried in hanger bracket 5I welded to cross angle iron 52 that is welded in turn to depending angle irons 53, 53 at each end thereof. The upper ends of irons 53, 53 are welded to angle irons 54, 54 disposed at an inclined angle lengthwise of the machine. Bearing .bracket 55 also supports power shaft 50 at about its middle part. It is welded or bolted to the center part of cross angle iron 58 of frame I.

Power shaft 50 has a universal joint at BI! and one at 6I. The lower link 52 of shaft 59 is connected to and rotated by the power take-off of the tractor, not shown. The upper end of power shaft 50 has mounted to turn therewith a bevel pinion 55 that meshes with a bevel gear 5G mounted to turn with shaft 44:

The means for elevating and lowering the rear of frame I relative to wheelsv'5, 5 contemplatesa rock lever handle mechanism disposed on one side of the machine, hereinafter described.

It embodies a bell crank lever handle 10 pivoted at 1I to rack frame 'i2 welded to frame bar 8. lThe lower right anglev part of handle 10 is pivoted at 16 to they bifurcated end of sleeve 11 that provides a loose t for the end of rod 18 which has a bearing in upstanding member welded to the horizontal part 19 of frame bar 8.

The opposite end o f rod 18 is pivoted-at 8| to bell crank lever 82 fulcrumed on rod 83 projecting laterally from plate 8A; welded to horizontal member 19 of frame I. 'Ehe opposite end of bell crank lever 82 is pivoted atY 95; to link 86 which has its lower end pivoted at Ill` to upstanding lug 88 welded to a crank of the crank axle 3. Rod 83 extends across, the machine and has an arm 8 9 that rocks therewith. Arm 89 is pivoted to a like link 85 similarlyconnected to axle 3.

When the handle 10 is released, the weight of the frame I will cause the crank axle 3 to rotate so that its oiset portion moves downward, thus lowering the rear end of the frame with respect to the wheels 5. The degree to which the near end of frame I can be lowered, however, will be determined by adjustable pin 90 engaging one of the series of apertures 9| made in rod18. The ends of pin 90 will project, far enough from the surface of rod 18 to abut against the contiguous end surface of sleeve 11, whichV is pivoted at 15 to bell crank lever handle 10 as abovementioned and as hereinafter explained.

Handle 'I0 is tted with :a sliding dog 95 having a tooth that is adapted to engage any one v of the series of notches 96in rack 12. Dog 95 is actuated by handle lever 91 pivoted at 9S toy handle 10. It is connected to dog 95 by link 99.

The means for cushioning the rear ends of the pans I5, I5 from the rough places in the ground contemplates a coiled spring |00 mounted on rod 18 between :adjustable collar IOI and bearing member 80.

The means for elevating and lowering the front end of frame I relative to the ground embodies rod |02 pivoted at |03 to bell crank lever handle 10. The free end of rod |02 slides in sleeve |04 pivoted at |05 at its lower end to upstanding lug |06 welded to bar 6.

The means for cushioning the front ends of the pans I5, I5 embodies a coiled spring |01 disposed upon sleeve |04 between adjustable collar |08 and collar |09. The latter is mounted to slide on sleeve |04. Collar |09 is connected to upstanding lug ||0 welded to the downward inclined part of side frame bar B by a link III, whereby the shocks of pansv I5, I5 will be4 absorbed by spring |01.I

rhe means for limiting the downward movement of the front part of frame I embodies an adjustable pin II2 projected through one of a plurality of apertures |I3 made in rod |02. It extends therebeyond on either side to engage the contiguous end of sleeve |04.

In order to prevent the machine from tearing the vines from the ground it is necessary to holdrakesT-I I5, II5 at an inclined angle thereto, whereby the forward part of rakes II5, II5 will be higher from the ground than the rear part of rakes I I5, I I5. This will permit the forward part of rakes I I5, I I5 to contact the upper part of the vines and the rear part to contact the lower part of the vines as the machine approaches the same.

The means for tilting the sub-frame carrying pans I5 and chute'26 relative to frame I contemplatesupStanding brackets |I1, III on opposite sides of the pan sub-frame and each provided with a plurality of apertures II8, IIS. Brackets I I1, II1 are bolted or welded at their lower ends to'cross angle iron I *I9 of the sub-frame. The

` upper ends of brackets II'I, II.' lie adjacent the side bars 8, 8 of frame land are detachably en-v gaged rtherewith by adjustable pins |20, |20 inserted through theA pre-determined apertures I IB, IIS in brackets II1, II'I and into an. aperture made in said bars 8, v8. A

The means for picking the beans contemplates said rakes II5, II5. mentioned above mounted to move alternately7 in a elliptic and at an inclined angle towards the rear ofA the machine, whereby to rake the beans from the vines, rst from one side and then the other. Moving in :an elliptic will cause rakes II5, II5 to move inward to contact the vines, then upward to pull the pods off the vines and then let them fall upon the conveyor belts I2I, I2I located on either side of the machine-.

Belts |2I, I2I lie adjacent belts 20, 20 and are not provided with cross slats, whereas belts 20, 29 are provided with slats |22, |22. Said belts I2 I, `I2I travel upon the same front rollers 2|, 2i as ldo belts 20, 20. At the rear, however, they travel on rollers |23, |23 having bearings in sidewalls 22, 22Y of pans I5, I5 and are located near the center of pans I5, I5.

In order to have the surface of belts I2 I, I2| a little above the surface of belts 20 to allow the beans to move thereon the diameter of rollers 2|,1 2| and |23, |23 are larger at the end over which belts I2I, |2I travel than the end where belts- 20, 20 travel.

This will enable the pods of beans ,to move onto belts 25, 20 when they come in contact with the scrape-orf members |24, |24 disposed at an angle to belts |2I, |2I.

The scrape-ofi members |24, |24 are welded or otherwise secured to and supported by. inclined members I2 5, |25 that extend between the scrape-off members |24, |24 and the front of the machine to overlap belts |2I, |2I toform an inclined plane for the pods to slide downward thereon and to close the gap between walls 22, 22 and conveyor belts I2I, I2 I, whereby the pods cannot fall in between said walls 22, 22 and belts |25, |21. The inclined members |25, |25 may be formed integrally with or welded to the vertical guide walls |95, |96 hereinafter described.

The means for` actuating rakes II5, II5 heretofore mentioned contemplates a pair of yokes E30, IBI for each of the rakes II5, II5. The forward yoke |30 of each set is mounted to turn freely on the bearing part of a crank arm |32 which has a tight fit to the reduced forward end of shaft |33 disposed on an incline ldownward towards the rear of'the machine.

assists;

5. Shaft |33 has loose bearings in hangerstraps |34, welded to cross angle irons |36, |31 respectively, whereas the rear yoke |3| of each set is mounted to turn freely on the bearing part of crank arm mounted to turn with shaft |4I located in the same plane above and parallel to shaft |33. Shaft I4I turns freely in bearing straps |42, |43 welded to cross angle irons |44 and of frame I respectively.

The means for revolving each pair of shafts |33 and I 4I in unison and in the same direction contemplates a sprocket Wheel mounted to turn with shaft I4I, sprocket wheel mounted to turn with shaft |33, and connecting sprocket chain |52. The lower shaft |33 of each set acts as the power shaft. To this end a bevel pinion |53 is mounted to turn with each of the shafts |33, |33 which lay parallel to and in the same plane to each other. Said pinions |53, |53 mesh with beveled pinions |54, |54 mounted on the ends of shaft 44, which is rotated by power shaft 50 as hereinabove described.

Each pair of the yokes |30, |3| of each set rocks not only on the bearing parts of crank arms |32, |40 but also because of the connection of crank arms |32, |40 to shafts |33, |4I to travel in a planetary motion about the ends of shafts |33, I4| ascenters.

The means for causing rakes I I5, |I5 to travel in an elliptical path, whereby they will move inward from opposite sides towards the vines, then upward to. rake the beans from the vines, and outward to clear the vines on their downward strokes embodies a pair of links |60, |6| hereinafter mentioned. Said links |60, |6| limit the rocking of each pair of yokes |30, |3| on said crank arms |32, |40. The bifurcated upper ends Qf each of the links |60, |6| is pivoted at |62 to one end of each of the yokes |30, |3| respectively, and the lower ends of each of the links |60, |6| is pivoted at |63 to each of the rigid cross angle irons |64 and |65 respectively of frame I.

Furthermore, the elliptic movement of rakes H5, ||5 contemplates a pair of links |10, |1|

pivoted` at their upper bifurcated ends at |12,

|13 vto the opposite free ends of yokes |30, I 3|. The lower ends of links |10, |1| are formed with horizontal outstanding shelves |14, |15 in each instance. Shelf |14 has an aperture for the upward projection therethrough of sleeve |18, whereas shelf |15has an aperture for the upward projection of rod |11 having a sliding t with sleeve |16 and held thereto by set bolt |18. The lower ends of each of the sleeves |10 is bored for the projection of a pin |19 having bearings in upstanding ears |80, |80 in each instance that are welded or otherwise secured to the'tubular back part |8| of rake |I5. Teeth |82 project laterally from tubular part I8I of rake I|5.

Links |10, I1| are pivoted at |83 to grooved members I 84, I 85 that slide on depending bars |86, |86 in front and bars |81, |81 in the rear respectively. Each of the bars I 86, |86 and |81, |81 are bolted or welded .to cross angle irons |36 and |64 of frame in the front and cross angle irons |65, |45 of frame I in the rear respectively.

: As shown inFig. '7, when the left hand set ofcrank arms |32, |40 rotates clockwise with lshafts |33 and I4I, carrying the left-hand yokes |30 and 3| therewith, said yokes |30, |3| will lower and move outwardly the left-hand rake -I I5, 'whereas the right-hand set of crank arms, which 'arevin parallel relation to the left-hand 6l set .of crank arms as seen in Fig. 5 will rotate counter-clockwise with the right-hand shafts |33, I4I carrying the right-hand yokes |30, |3| therewith, and said yokes will move the righthand rake II5 inward and upward to rake the bean pods off the vines.

It will be observed that each set of yokes |30, |3| have two independent motions. They will move with crank arms |32 and |40 in a planetary manner 'and also rock on the bearing parts of said crank arms.

The means for blowing foreign matter from the pods embodies a fan I0 mounted to revolve in a casing attached to the rear en d of chute 25 hereinabove mentioned. It is revolved by a V-belt |92 connecting pulley |93 on shaft |94 having bearings in casing I9| and V-pulley |95 mounted to turn with shaft 44.

The means for holding the vines as they are being combed by rakes ||5, ||5 contemplates yielding vertically disposed guide walls |96, |96, resiliently supported by the side walls 22, 22 of pans I5, I5 hereinabove mentioned. The front free ends |91, |91 of walls |96, |96 curve outwardly away from each other to allow for co1- lecting the vines therebetween.

The means to allow walls |96, |96 to yield when contacting the vines, whereby to aid in preventing the vines from being pulled up, contemplates several spaced sets of pairs (seen at the bottom of Fig. 1) of rods 200, 200 mounted in bearings in walls 22, 22 of pans I5, I5.

As shown in Fig. 6, the inner ends of the rods 200 are welded or otherwise secured to the walls |96, and the outer ends of each pair of rods 200 are connected by a spacer plate 20| to which the rods are held by nuts threaded thereon. A coil spring 202 is mounted on each ofthe rods 200 between the spacer plate 20| and a stop collar 203 secured to rod 200, for example, by being threaded thereon ^or pinned thereto. A strut 204, T-shaped in section, is located between and parallel to each pair of rods 200, and has its ends welded to the sidewall 22 and the spacer plate 20|. `The assembly thus described is suspended within the pan I5 between the upper and lower reaches of the conveyor belts, and serves to resiliently support the guide walls |96 at a fixed minimum spacing, while permitting them to yield laterally outward when subjected to any undue This means for separating the vines from rakes II5, ||5 as they approachtheir high position contemplates strippers 205, 205 disposed in parallel relation'and hung lengthwise of the machine by bars 206,206 fastened to cross angle iron |64 in front and to cross angle iron |65 in the rear. Each of the strippers 205, 205 is provided with vdepending teeth 20? that are disposed to enter the interstices between teeth |82 of rakes l5, I I5. In operation the machine will be attached to a tractor, not shown, by means of clevis l0. The tractor will straddle the vines as it moves along 'the rows thereof and draw the machine therebehind.

In Figures l and 2, the machine is shown disconnectedfrom the tractor and in a position of repose such as it would occupy when resting on a smooth floor.v In operation, the front endof the frame I is supported by the tractor as above described. In moving the. machine to a bean eld along a road or lane, or over a headland between rows of bean plants, the handle 10 is pushed down to raise the entire mechanism well abovethe ground for convenient transportation, When picking, the handle 10 is pulled up assises to lower the mechanism to the positions determined by the adjustments' of the pins 90, ||2 and |20 as described below. In such` service position, the main frame isv adjusted so that the rakes |15' are tilted upward and forward to such an extent that the front ends of the rakes will contact the bean plants near the uppermost pods and the rear ends of the rakes willcontact the bean plants near the lowermost pods. Also', the sub-frame is pivoted within the hanger bearings l relative to the main frame so that thev pans i are in contact with the ground at theiry rear ends and are tilted a little upward and forward so as not to digl into the ground as the machine is drawn forward. The springs |00 and |01 permit the frame to yield and move upward when the pans l5 encounter any' roughness in the ground.

Proper adjustments for the degree to which frame can be lowered will be made by plugging pin 99 in a predetermined aperture 9| of rod 18 and pin ||2 in a predetermined aperture I|3 of rod |02. Proper tilting of the sub-frame withv respect to the main frame is obtained by plugging pins |20, |20 in selected apertures H8,v ||8 in brackets |l1, |I1'.. The. motor, not shown,.will` be started to revolve. master shaft 50 which will rotate pinion 65 thereony and bevel gear 66. fixed to turn with shaft 44..

The. turning of shaft 44 willY revolve sprocket 43. connected' to sprocket 40 by sprocket chain 42, whereby to actuate conveyor belts 20, 20 and il, |2115. V-pulley |95 fixed to. turn with` shaft 44 will rotateV-pulley |93 fixed to turn with shaft |94, whereby to actuate fan |90.

Furthermore, shaft 44 will rotate bevel pinions |54, |54 whichmesh with bevelpinions |53', |53 to turn shafts |33 andl |4|` located in pairs on each side of the machine. Shafts |33, |4| will rotate in unison and inthe. same direction through the medium of sprockets |50, |51 and sprocketchains Each pair of shafts |33, |4|` will rotate crank arms |32, |40= to actuate yokesV |30, |.3| in a planetary manner. Links |60, |,6|: pivoted at their upper ends to one end of yokes. |30, |3| respectively and at` their lower ends to cross angle irons |64 and |65, will cause yokesv |130, |3| to rock on the bearing parts of crank arms |32, |40, whereas links and |1| connected at their upper ends to the opposite end of yokes. |30, |3| and at their lower ends to rakes ||5,y ||5f, and carrying groovked members |84, |85 that slide on depending barsv |86, |81, will cause said rakes |5, ||5 to move in an elliptic path, whereby'to rake the bean plants, snap off their pods andY allow them to fall on conveyor belts |2 |2 l, where they are pushed oli by members |24, |24 onto conveyor belts 20, and then carried towards the rear and upward through chutes 26' aided by sheet.

3| and thence out into a bag, not shown, through nozzles 2|0, 2|0. Fan |90 will blow the. foreign matter out through openings 2| 2|.|.

As the machine moves through. the. rows' of vines, yielding walls |96, |96 will have ani easy approach thereto becauseof thecurved` outwardly extending parts |91, |91 of walls |96,. |96 and because of their tilted position with' relation to the ground. Walls |96, |196 will hold the vinesv from being torn up by their roots, while4 rakes H5, H5 will comb 'the pods of beans from said vines.

As the'rakes move off they will pass through the strippers 205, 2'05-to wipe off' any vines that are pulled up, whereby to:leave-therak'es |15, |l| 5 free from foreign matter.

'lor

Ina-smuchf as the;1 pods of beans hang downward and the action of the rakes is upwards, the rakes |5, I5 will snap off the stems of the pods from the vines, without bruising or damaging the. bean pods.

The adjustment of pins and H2' will allow for tipping the frame and the rakes ||5, Il'5' at a predetermined angle, whereby' the. rakes H5, ||5 will approach the vines with the front part of said rakes nin contact with. the upper part of the: vines, and the rear part of said rakes. in con'- t'act with the lower part of the vines. This ape proach will aid also to prevent rakes H5, ||5 from tearing. the vines: from the. groundV as ex'- plained above.

Figs. 8 to 13, inclusive,l and' Figs. 14: and 15, show two modified machines differing from thev machine already described primarily in the form of the rakes.. The rakes shown in these modiiiY cations can be substituted for the rakes |'|5' on the same framework above described in conf nection with Figs- 1 to 7, inclusive, with slight changes'- inv the parts of the frame that support the driving mechanism for the rakes.. Referringy now to. Figs. S to 13, inclusive, there are shown rakes 22'0, 220 on either side of the machine` Said. rakes 2210, 220 embody sleeves. 22|, 22|. which rotate on crank shaft 222 having bearings at 2:23'. and 224 in casings or. housings'. 225 of the machine. Sleeve 22| has an arm` 226 connected' to. bearing 2.21 which carriespin 228 that projects in: the boss'. part 229. of sliding member 230 with a tight'` iit. Member 230 Slides on shaft 23|', whereby to effect the same. motion as. heretofore described relative to rakes 5..

Slots 232 in casing 225 through which the. teeth 233 ofi rakes 220, 220 project allow for an upward and inward motion of said teethi233 and alsp allow the. casing 234' adjacent the opening to act as strppers.y Each of the casings: 225 isheld. at anl inclined angle as shown ini. Figs; 8k and; 9 by angleiron'si 235 and 236V to angle bar 231 of the frame.

rEhe means for rotating crank arm. 222- embodies a sprocket and chain combination 240 with shaft 242' held to turn. in, bearing straps 243, 2'44 attached .to cross angle. irons 2'45, 246. Angle irons 245 and 246 are welded toangle irons 24T andf 248. Angle irons 24.1; and 248' are welded at their lower ends to frame bar. 2505 and at their upper endsto. frame bar'2 5|.

Shaft 242 has a bevel'pinion 252 adapted to turn therewith andA meshing' with its counter bevel pinion 253 fixed to turn with' cross shaft 254 supported in bearings in' the. frame; Bevel piniorr 255 is mounted to turni-with shaft 254' and meshes withV bevel pinion `256 xed toVY turn with power shaft 251.

Figs. 14 and'. l5 show a still further modification showing a drum. rake 260 having av rowl of teeth or tines 26| at diametrically opposite positions. The teeth 26|' comprise wires that. are wound' around shafts. 262,y 262. Drum'V 269 is revolvedv by a sprocket' and?. chain:v connection 265 with. shaft 266 having" a bevel pinion? 2611 that meshes with bevel' 260 mounted to turn with cross shaft 269: which' carries a bevel gear 210 meshing with a bevelpinion 21| mounted to turn with power shaft 212.

The machine. of Figs; 14 and 1`5 has' only: a single. drum; rake operating on` the: bean. plants from oneV side'V of the row, but the arrangement of thedrum rake2||lA is? such thatl thezb'ean. plants may beiy completely picked from.A one side; 'I'his drum raket machinel is' particularly" useful for the last"- pickinig or bean plantsV that. ripen'. in

stages, or for the picking of' bean plants of a variety the pods of which ripen substantiallyall at the same time so as to reqiure only a single picking, since lit tines 26|, in passing through to the' far .side'f't'he plants, subject them to a somewhat roughe'action thatis apt to strip a considerable number of'leaves from the plant.

Having thus described my invention, what I claim asmne'w and desire to secure by Letters Patent is asV follows: p

1. A bean picker adapted to pick whole bean pods direct from bean plants rooted in the ground, comprising in combination a mobile frame adapted to be transported forward along a row of bean plants, a rake mounted on said frame substantially longitudinally thereof for movement with respect to said frame, said rake including longitudinally spaced tines adapted to engage the bean plants from one side thereof in succession as the frame moves forward, means on said frame and operatively connected to said rake for moving said rake relative to said frame in such manner that the tines move in an endless path, said path having a portion adjacent said one side of the plants in which the tines move within and up said bean plants, whereby tines passing under bean pods may sever the pods from the plants at their stems, said rake being so constructed and arranged that the successive tines make initial engagement with each 2 transported forward along a row of bean plants,

a rake mounted on said frame substantially longitudinally thereof for movement with respect to said frame, said rake including longitudinally spaced tines adapted to engage the bean plants fromr one side thereof in succession as the frame moves forward, means on said frame and operatively connected to said rake for moving said rake relative to said frame in such manner that the tines move in an endless path, said path having a portion adjacent said one side of the plants in which the tines move within and up said bean plants, whereby tines passing under bean pods may sever the pods from the plants at their stems, said rake being inclined upward and forward with respect to said frame so that the successive tines make initial engagement with progressively lower portions of each bean plant, whereby the pull tending to uproot the plant is minimized, and means for catching the severed bean pods as they fall toward the ground.

3. A bean picker adapted to pick whole bean pods direct from bean plants rooted in the ground, comprising in combination, a mobile frame adapted to be transported forward along a row of bean plants, a rotary rake mounted on said frame substantially longitudinally thereof, said rake including longitudinally spaced tines adapted to engage the bean plants from one side thereof in succession as the frame moves forward, means on said frame and operatively connectedto said rake for rotating said rake in such direction that the tines move within and up said bean plants, whereby tines passing under bean rods may sever the pods from the plants at their stems, said,

rake being so constructed and arranged that the successive tines'make initial engagement with each bean plant progressively along the plant fromxthe top down, whereby the pull tending to uprootthe plant is minimized, and means for catching the severed bean pods as they fall toward the ground.

4. A bean picker adapted -to pick whole bean pods direct from ybean plants rooted in the ground, comprising in combination, a substantially horizontally disposed mobile frame adapted to be transported forward along a row of bean plants, a rotary rake mounted on said frame substantially longitudinally thereof, said rake including longitudinally spaced tines adapted to engage the bean plants from one side thereof in succession as the frame moves forward, means on said frame and operatively connected to said rake for rotatment with progressively lower portions of each bean plant, whereby the pull tending to uproot the plant is minimized, and means for catching the severed bean pods as they fall toward the v ground.

5. A bean picker adapted to pick whole bean pods direct from bean plants rooted in the ground, comprising in combination, a mobile frame adapted to .be transported forward along a row of bean plants, a pair of rakes mounted on opposite sides of said frame substantially longitudinally thereof for movement with respect to said frame, each of said rakes including longitudinally spaced tines adapted to engage the bean plants from one side thereof in succession as the frame moves forward, means on said frame and operatively connected to said rakes for moving said rakes relative to said frame in such manner that the tines move in an endless path, said path having a portion adjacent said one side of the plants in which the tines move within and up said bean plants, whereby tines passing under bean pods may sever the pods from the plants at their stems, said rakes being so constructed and arranged that the successive tines make initial engagement with each bean plant progressively along the plant, from the top down, whereby the pull tending to uproot the plant is minimized, and means for catching the severed bean pods as they fall toward the ground.

6. A bean picker adapted to pick whole bean pods direct from bean plants rooted i n the ground, comprising in combination, a substantially horizontally disposed mobile frame adapted to be transported forward along a row of bean plants, a pair of rakes mounted on opposite sides of said frame substantially longitudinally thereof for movement with respect to said frame, each of said rakes including longitudinally spaced tines adapted to engage the bean plants from one side thereof in succession as the frame moves forward, means on said frame and operatively connected to said rakes for moving said rakes relative to said frame in such manner that the tines move in an endless path, said path having a portion adjacent said one side of the plants in which the tines move within and up said bean plants, where- .by tines passing under bean pods may sever the pods from the plants at their stems, said rakes being inclined upward and forward with respect to said frame so that the successive tines make initial engagement with progressively lower por- 11 v T 12 tions of each bean plant, whereby the pull tend- UNITED STATES PATENTS ing to uproot the plant is minimized, and means Number 'Name Date for catching the severed been pods as they fall 13711372 Savage k Oct. 11 1387 'toward the gfound- 637,281 Pence Nov. 21, 1899 LEILA B.
